Abstract
A system to suppress sound emerging from speakers and the generation of same at a distance is presented. This system includes devices to handle audio which when manipulated, in their different applications, are capable of reducing or of eliminating the acoustic impact or sound unwanted by people or by the environment. The present system includes a combination of known devices to handle audible signals or sound that allow for the analysis of the characteristics or specifications of sound or for the generation of an identical signal which can be inverted and mixed with the output signal to cancel sound and at the same time to suppress the inverted signal at a distance and in this way to once again generate sound at a distance. Considering the above, the scope of the present invention falls within the scope of the universe to transmit, mix, and suppress sound.
